Criticism of others is futile and if you indulge in it often you should be warned that it can be fatal to your career.
Dale CarnegieOne of the worst features about worrying is that it destroys our ability to concentrate. When we worry, our minds jump here and there and everywhere, and we lose all power of decision. However, when we force ourselves to face the worst and accept it mentally, we then eliminate all those vague imaginings and put ourselves in a position in which we are able to concentrate on our problem.
Dale CarnegieNeither you nor I nor Einstein nor the Supreme Court of the United States is brilliant enough to reach an intelligent decision on any problem without first getting the facts
